[PATCH AUTOSEL 6.14 319/642] Octeontx2-af: RPM: Register driver with PCI subsys IDs

From: Hariprasad Kelam <hkelam@marvell.com>

[ Upstream commit fc9167192f29485be5621e2e9c8208b717b65753 ]

Although the PCI device ID and Vendor ID for the RPM (MAC) block
have remained the same across Octeon CN10K and the next-generation
CN20K silicon, Hardware architecture has changed (NIX mapped RPMs
and RFOE Mapped RPMs).

Add PCI Subsystem IDs to the device table to ensure that this driver
can be probed from NIX mapped RPM devices only.
